SAFETY-RAZOR.

Application filed March 24, 1919.

To @ZZ whom t may concer/n.'

Be it known that I, PHrLrr H. NSINGER, a citizen of the United States ofAmerica, and resident of Geneva, in the county of Ontario, in theV Stateof New York, have invented new and useful Improvements in Safety-Razors,of which the following, taken in connection with the accompanyingdrawings, is a full, clear, and exact description.

This invention relates to certain improvements in safety razors.

An object of the invention is to produce a safety razor of relativelysimple construction and mechanical operation in which there ispractically no danger of the user cutting himself in assembling ordisassembling the parts. .Y

Another object relates to the efficient an positive nature of theholding .or locking means for securing the parts in position for use.

A further object relates to the production of a combined plain andtoothed guard in which the plain guard or guard bar is positioned inadvance of the teeth and from which the teeth project somewhat upwardlyand rearwardly toward the blade to. have a smoothing rather than adigging effect. The teeth terminate beneath lthe blade and are of such alength as to insure freedom of the beard from being forcedagainst theface both before and duringcutting. The guard bar preceding the guardteeth avoids sharp corners coming in contact with the face and wipesatleast a portion of the lather from the face.

A further advantage resides in the ease and rapidity with which theparts may be assembled for use and disassembled as for cleaning orpacking or other purposes.

The other objects and advantages relate to the details of constructionas will more fully appear from the following description taken inconnection with the accompanying drawings in which Figure l is aperspective view of the safety razor taken from the rear.

Fig. 2 is a section on line Qf-2, Fig. 1.

Fig. 3 is a section on line 3-3, Fig. l.

Fig. 4 is a section on line 1 -4, Fig. 2.

The razor as shown comprises a base plate --1- preferably formed ofsheet metal having its front portion bent downwardly from the body ofthe plate and preferably lying Specification of Letters Patent.

to constitute when formed as hereinafter described a guard bar and aseries of upwardly and rearwardly extending guard teeth. For thispurpose the plate has a portion cut away to form an elongated openingn2- bordered by relatively narrow sidewalls --3- and a narrow integralbar -4` constitutng the guard bar of the razor. A series of guard teeth-5- project into the opening -2- and when the front portion of the plate-1- is bent downwardly about an axes extending through the intermediateportions of the side walls K3- these teeth extend vpreferably forwardlyand rearwardly toward a blade -6- when properly-seated upon the base-1-. The opening -2 extends some distance tok the rear ofthe front at anobtuse angle with the body of the plate i edge of yblade and as vstatedthe teeth -5- terminate beneath the blade leaving a free passagebeneathlthe blade `for lather,

' hair, etc., the 'front edge of the blade at the side portions beingsupported by side walls 3 and preferably these walls are provided withstops -7- to properly limit and position the blade. Tbesestops -7- maybe formed in any suitable manner las by punching up parts of the platef1- or otherwise. The blade-G- is held in place Lupon the base f lby aclamping member formed'upon opposite' edges of the `rbase l-. The endVparts -10 may preferably be shaped as shown, the rear part beingsubstantially circular in form and the remaining portion of said parttapering forwardly and adapted to lie outside ofthe opposite edges ofbase -1- to inclose the blade except as to its projecting front edgeportion. The rear portion -13 of the clamping member -8 is preferablybent in substantially arcuate form to conform to the shape of the rearportion of parts 10- and forms a receptacle adapted to receive and holdthe blade when the clamping member is rocked about the plate -'lto itsbent position. For the purpose of locking or holding the clamping memberin proper position relative to the base -1- to tightly grip the bladeand hold it rigidly in position for use the rear portion -13- isprovided with a central flange 1% which may preferably be a symmetricalcondition of the said arcuate portion and extends toward the rear faceof the base -I and the base is provided with a cut out portion -l5forming a recess through which the flange 1-l` moves when the clampingmember is rocked about the base A1--. Y

It will' be understood that by exerting pressure on flange -l4f-- toforce it rearwardly away from the base -1 the clamping member -8- willbe rocked about the base -1- until its front edge tightly grips theblade 6* interposed between the clamping plate and the base and as thismember is formed of sheet metal of a more or less resilient nature theblade will be tightly and rigidly gripped with a spring tension thuspermitting slight variation in the size and relation of the partswithout affecting their efficient operation. For accomplishing thispurpose in a preferred manner the handle -16- may be secured to the base--1-n for rotary movement about an axis substantially perpendicular tothe` base and this may be accomplished by forming the handle with asomewhat enlarged head -17- having a recess 1S-- for engagement withscrew 19- extending through the base 1 and preferably having its headcountersunlr therein and constituting such axis. The head l7-` isprovided with a projecting lug 20- or member which may as shown betapered longitudinally and laterally and so positioned that upon rotarymovement of the handle -16- this lug is forced beneath the flange -14-to press the same rearwardly and effect the operation heretoforedescribed. The lug -20-- may be of somewhat angular or inverted V-shapeand the flange lll-- may be provided with` a small recess adapted toengage the peak of the lug when the parts are properly positioned tofrictionally roclr the same.

The handle -16- may if desired be formed in sections in the usual mannerand may be shaped in desired form to effect the most efficient operationof the blade -6- when positioned between the base and the clampingmember.

Although I have shown and described a specific construction, form andrelation of the parts as illustrative of a perhaps preferred embodimentof my invention, I do not desire to limit myself to the same as variouschanges, modifications and substitutions may be made in the detail ofconstruction, form, arrangementand operation without departing from theinvention as stated herewith in the appended claims.

What I claim is 1. A. razor comprising a base7 a clamping member pivotedtothe base and embodying a flangeextending from the rear of the fulcrumto a position at the opposite side of lthe base and in front of the saidfulcrum and a member movably mounted on the base and engaging the saidflange in front of the said fulcrum and acting to hold the clampingmember in blade gripping position.

2. A razor comprising a base, a clamping member pivoted to the rearportion of the base and embodying a flange extending from the rear ofthe fulcrum to a position at the opposite side of the base and in frontof the said fulcrum, a member movably mounted on the base and engagingthe said flange in front of the said fulcrum and interlocking parts onthe said member and flange.

3. A razor comprising a base, a clamping member pivoted to the base andembodying a fiange extending from the rear of the fulcrum to a positionat the opposite side of the base and in front of the said fulcrum, amember' movably mounted on the base and engaging the said flange infront of the said fulcrum and acting to hold the clamping member inblade gripping position and a handle secured to the base and actuatingthe said member.

In witness whereof I have hereunto set my hand this 17th day of March,1919.
